Corrosion protection circuit for conductor structure of automobile windscreen antenna using electrical passivation voltage as supply voltage for HF component

摘要

The corrosion protection circuit provides the windscreen antenna conductor structure with an electrical passivation voltage (Up), with circuit components, e.g. a bandpass filter (3B), a DC/DC converter (3W) and a smoothing stage (3S), allowing the passivation voltage to be used as the supply voltage for a HF component (3,3A) connected to the multi-pole line provided by parallel sections of the conductor structure. Also included are Independent claims for the following: (a) a method for operating an automobile windscreen antenna; (b) an automobile windscreen antenna.
